  1. Is the 5th generation header order still open?  Thanks.

    1. Duc2V4

      Duc2V4

      Manny, it’s not too late. I’ll send you a PM with the how-to place n order information. 
       

      For anyone else who might be interested, once Wade places the order and gets the pipes bent, then no mo orders can be taken.

  2. Hi Wingate - and thanks Rush for helping fill in a couple blanks. Short version - we hope Rapid Bike autotune feature adapts to 8 gens the same way it adapts to 2000-2001 5 gens and all 6 gens - that RB leaves the single 12mm OEM O2 sensor on the 8 gen connected and employs a single added 18mm wideband O2 sensor to send air/fuel readings to the RB. This is what the headers are configured for. But we are not certain whether this is the case. Yet. We hope. We selected one 12mm bung so guys who bought the new headers could still use their single 12mm OEM O2 sensor. VFRD member Samuelx, owner of the 8 gen test bike, is using Power Commander 5 and has kept his OEM O2 sensor and all is well - no FI warning light or other flags. It is not an autotune system. On Samuelx's bike we were able to use the 18mm bung for Attack Performance's wideband sensor when the bike was on their dyno - this is more accurate than a 'sniffer' inserted into the tailpipe. We did have to purchase a 12" extension cable for the OEM O2 sensor to reach back to the new headers' collector exit, because placing the 12mm bung in the collector exit pushed it 12" further back than the front-of-catalytic-converter position of the OEM bung. This position allows air/fuel readings from all four cylinders combined. [The O2 sensor extension cable sells for $11 on ebay and is described as being for Honda Civic autos. Do NOT purchase the 12" O2 sensor extension cable for Acuras you might find on ebay, as it looks like it uses the same connector, but it does not. Ask me how I know]. We added the 18mm bung to 8 gen headers - also in the collector exit where it samples gases from all four cylinders - so that the wideband O2 sensor that Rush2112 described as a "single Rapidbike wide band O2 sensor" would function properly on 8 gen VFRs. We know the Rapid Bike autotune can use the third [wideband] sensor along with the two OEM sensors on 2000-2001 5 gen VFRs and all 6 gen VFRs [Duc2V4 is using this setup on both his 2001 and on his 2009]. After checking in with Duc2V4, neither of us are certain that one must use three sensors with a RB autotune on 5, 6, OR 8 gen VFRs. This is strictly a guess on my part, but it might be that RB sets up their autotune system to use the two OEM sensors on VFRs that have two OEM bungs/sensors simply because the two bungs are there, and they both happen to be full of sensors. I think I recall that with RB wideband sensors are an upgrade option, but OEM narrow band can be used - I could be wrong here. Duc2V4 can speak to this [And I hope he will - I'm floundering a bit]. What we hope for 8 gen owners who purchase new headers and are aiming for a RB with autotune is that RB sets up their system for 8 gen to use one 18mm wideband O2 sensor in conjunction with the single OEM sensor in the 12mm bung. [Please note the amount of restraint required to not add 'hole' after 'bung'] Since I'm listing and describing things I do not know, I'll add that I do not know if the the 8 gen's single 12mm OEM O2 sensor is wideband or narrow. The new performance 8 gen headers have an 18mm bung because 18mm is the size we know for certain that quality Bosch wideband O2 sensors come in; they are sold by both RB and Dynojet [Power Commander] and are used by most dyno tuning facilities. Bottom line - more research is needed. **Anyone who can help develop a definitive answer to how an 8 gen VFR implements a Rapid Bike autotune system, please do chime in here**
  3. Confirming what Duc2V4 said - the maps will be here and available on an ongoing basis.
  4. Jozef - our favorite dyno technician in the world and head of tuning at Attack Performance - has provided the maps he built on the dyno for: 5 gen VFR800 tuned with Power Commander 3 6 gen VFR800 tuned with Power Commander 5 8 gen VFR800 tuned with Power Commander 5 These maps will work well on any 5th, 6th, or 8th gen VFR800 with the new performance headers, a good quality hi-flow air filter [We prefer the K&N HA-8098 filter] and a good quality slipon muffler. If you have purchased these headers and would like to utilize one of these maps to optimize your VFR's performance without trucking it out to a dyno shop, we can email the map for your gen VFR to you for a donation of $50. Please send 'sending to a friend' to the paypal account of vfrheaders@gmail.com, and in the note section of the paypal transfer, specify the email address you'd like us to send the map to. Below are the dyno charts for the three maps. These maps were posted early on in this thread, but are included here to save people the trouble of locating them in the way-back portion of this thread. Each chart has three traces: [1] a baseline run with OEM headers [2] a run done with the new headers installed and a zero map, meaning no tuning and no changes to OEM ECU fueling were entered into the Power Commander map [3] a final run after a complete tune was performed There are two versions of each chart: [1] a chart with a reference line at peak horsepower/torque [2] the same chart with a reference line at midrange 7000rpm to demonstrate the midrange gains achieved with tuning the new headers [8 gen kicked butt at 7000rpm with 16% gains in both horsepower and torque] 5 gen Power Commander 3 map [peak]: 5 gen Power Commander 3 map [midrange]: 6 gen Power Commander 5 map [peak]: 6 gen Power Commander 5 map [midrange]: 8 gen Power Commander 5 map [peak]: 8 gen Power Commander 5 map [midrange]:
  5. NO LONGER AVAILABLE This 1991 3rd gen VFR750 has clean non-salvage Arizona title Rear wheel NOT included, but the good condition, straight OEM 5/6 gen rear wheel/tire in photos can be had for $150. Does include all the following: - all powertrain parts engine, carbs, airbox, etc - OEM headers - straight frame, swingarm, forks - straight front wheel - dent-free gas tank [one scrape - see photo] - seat [tired but no rips or holes] - handlebars/controls - complete undamaged instrument panel/gauge cluster - complete front and rear brake systems - everything else in photos except rear wheel Available for local pickup in North San Diego county. I am posting it here for a week in case a VFRD member has been looking for a 3rd gen project. After a week it gets listed as free to the vultures on craigslist. No offense to craigslisters - sometimes I'm one of the vultures, too.
  6. There has been progress. First please allow me to thank Duc2V4 for his patience and persistence in supporting and encouraging continued effort on this project - he is a rock star in many ways, more even than are evident in his high quality participation on VFRD. Second, please allow me to sincerely apologize to everyone - especially those who have placed deposits for headers - for not staying current with communication regarding this project. No excuse can suffice for me dropping the ball the way I have. I will be paying close attention, responding promptly, and doing my part from here on out, beginning with reading through/responding to all PMs and catching up on the many posts on this thread that I missed. We have been able to arrange with Wade, the fabricator of VFR headers, to complete construction of fifteen sets of 8 gen headers, in spite of not having met his minimum quantity of fifteen orders. These 8 gen systems have been built on a jig that was modified slightly to provide better fitment when the center stand is down. Seven of these fifteen 8 gen headers are already sold to VFRD members and to a couple others who placed deposits. Again, thank you all for your patience. Eight sets of these 8 gen headers are now available for purchase. Going forward, Wade has also finally agreed to build runs of as few as 6 sets of headers, down from a minimum order of 15 units. Because of this, those who have placed deposits for 5/6 gen headers in the second production run will be seeing their headers built soon. This also means a much shorter time between production runs for all headers, 5/6 gen and 8 gen. For upcoming 5/6 gen headers, Wade has modified the jig to provide better center stand clearance, as well as establishing clearance between the front right primary tube and the inner chin half cowl. Ten of the 8 gen headers that have been completed are currently at the passivators being acid dipped for strength and longevity. Passivation costs $90 per exhaust and has been discussed in detail early in this thread, starting with Sebspeed's querie on page 2: https://www.vfrdiscussion.com/index.php?/forums/topic/88463-new-5th6th8th-gen-performance-header-now-in-production-in-usa/page/2/] The five remaining 8 gen headers can be passivated if the buyers chooses to do so. To begin getting headers shipped out to their new owners, PMs with more detail will go out in the next 24 hours to all those who have placed deposits for 8 gen and 5/6 gen headers. We have also checked in with Tyga about their upcoming headers, and received an interesting reply. Here is the email exchange [with names and personal emails removed]: "> -----Original Message----- > From: ______ _______ [mailto:____________] > Sent: Friday, September 20, 2019 10:48 PM > To: Tyga-Performance <Tyga@Tyga-Performance.com> > Subject: Enquiry from TYGA-Performance: New Tyga headers for Honda VFR800 > > Hello, > > I just saw the Tyga update on the vfrdiscussion.com website - it is exciting to learn that Tyga will be producing headers and exhaust systems for the Honda VFR800. > > Are you far enough along in the process to have pricing for a set of headers for the VFR800? > > Which version or versions of the VFR800 are your headers going to be built for? 5th gen with two side-mounted radiators is 1998-2001, 6th gen with two side-mounted radiators is 2002-2013, and 8th gen with one front-mounted radiator is 2014-2016. > > Thank you very much for following through on this project. > > Best regards, > > ____________ > On Sep 22, 2019, at 9:29 PM, tyga <tyga@tyga-performance.com> wrote: > > Hi _________ > > Many thanks for the message. We are actually making the exhaust for the 1993-97 model. I am not sure if it will fit previous or subsequent models. I understand that the TBR one fits earlier models but not sure if they would be compatible with the 800. Our plan would be to get the 4th gen to market and see how they sell and hopefully, if it is successful, we can then adapt as necessary to fit earlier and or later models. Sorry, it looks like your wait will need to be a bit longer. > > Best regards > > Paul >" Postscript - we were able to work with VFRD member SamuelX and his beautiful 8 gen [Deluxe model] to develop this high mount exhaust to go with the headers. SamuelX wanted to keep his Yoshimura muffler, so we trimmed it to fit the bike's dimensions. I have had the privilege to ride this motorcycle on several of my favorite sets of twisted pavement. With the added performance, this bike was an awful lot of fun - thanks Samuel! For the first time, I starting thinking that perhaps the 5 gen is not the be-all, end-all of VFRs...
  7. Is it too late to get a set of 8th gen headers?

    1. Duc2V4

      Duc2V4

      The short answer is no, in fact we need to get more 8 Gen orders, so if you know of any other 8 Gen owners who are not aware of this header or not on the forum (they should be!) let them know.

      Hi camspar,

       

      As Duc2V4 confirmed, nope, it’s not too late for 8 gen headers. Wade the fabricator has actually built  number of 8’gen headers, and they will be available in short order, ready for shipping in about 2 weeks.

       

      If youd like a set, let us know by making a $200 deposit to the paypal account associated with vfrheaders@gmail.com. In the note section of the pp transfer, please state the following info so we can track your order and get it on its way:

      -vfrd username

      -8 gen

      -whether you want an 18mm O2 sensor bung  for an auto tune system. The second bung also allows a dyno tech to get better readings on air/fuel ratio. The headers do come with one 12mm bung to accept the single OEM O2’sensor.

      -shipping address

       

      We will message you with confirmation that we received your deposit.

       

      Thanks,

       

      Lance and Darryl

  8. Hey #3, nice touch painting the lock mechanism black.
  9. I’m jumping in without reading entire thread, so apologies if this has been covered. Check in with Sebspeed about the simple stainless Y bracket he builds to replace right side passenger rearset.
  10. Looks great capn. I never got to hear the Wolf with the new packing installed and quiet inserts removed - I bet with the TBR headers it is schweeet! Getting to have a listen to your bike is another reason for us to get out on a ride together.
  11. There has been a lot of activity since I was last staying up with events on this thread - all good stuff, even the teething problems. I sincerely apologize to everyone here for being off the reservation. I am currently in the high Colorado mountains and clinging to a one-bar signal that literally blows away when the wind moves. I will be back on reliable internet Monday and will thoroughly flesh out the points below. I have not been idle...Wade and I have been talking regularly about: (1) plans to finish the production run of 8 gen headers and sell from stock without waiting for 15 deposited orders. Wade is considering this. (2) modifying his jigs to move cylinder #1 primary 1/4” to the right, as there is slight interference with the center stand at the bottom of its arc. This occurs on my bike and the 8 gen w prototype headers, perhaps others? (3) gearing up further to do another run of 5/6 gen headers. On 5 and 6 gens cylinder 4 (front right) clearance with the inner half ‘chin’ cowl is a problem. The TBR headers get very very close at this point, and our production headers touch the chin cowl. Here are the TBR installed on a 5 gen: On my 5 gen heating the chin cowl with a heat gun and flexing it forward where the headers touch provided enough clearance to avoid melting plastic. The blue tape is how I marked the area to heat and flex: I just found out this internet connection can’t handle full res photos, so I’ll reduce the image sizes and insert then into this post as an edit later today. More to follow.
  12. Cool - thanks Seb. A clear topping coat is a good idea - like adding whipped cream to anything - might very well lighten things up. I will check w the applicator and see if he’s up for a test.
  13. Here’s the admittedly subtle difference between Honda Pyrite Brown Metallic (8 gen accent color) and the way my powdercoater applied Prismatic Triple Bronze. I recommend that anyone having powdercoating done with a specific color in mind have a test part done or at least get color swatches.
  14. Hey Sean - I love the Triple Bronze too, and it definitely was a perfect match for MiniCarver's 8 gen components. But I went astray by not getting color swatches from Prismatic or, even better, paying my applicator to buy a small amount and powdercoat a test piece. I had a pair of wheels, 2 valve covers, a clutch cover, and three calipers coated in Prismatic Triple Bronze and they all came out a lovely darker, greener color than the 8 gen wheel/component color. After facing the consequences [cost] of my mistake, I contacted Prismatic and learned that they have a four tier color matching program. You send them a part that is the color you want to match, then they do either a [1] Quick Search - a no-charge search of all their current colors with no minimum purchase. They then send you 2-5 swatches of the colors they've found closest to your color for $6 shipping [2] Archive Search - no charge for the search, but there is a 6 pound minimum purchase [Powdercoat powders run roughly $11-15 per pound]. They search 6500 colors and textures they have on file, then send color/texture swatches [unspecified quantity] closest to the part you sent for $6 shipping. [3] Reformulation - the Prismatic description of this process is not entirely clear, but the service costs $100 to provide swatches, and carries a 10 pound minimum purchase. [4] New Formulation - again the description is not clear, but does involve terms like 'chemistry' and 'complex'. This service costs $400 to produce a sample of the color, requires a 45 pound minimum purchase, and takes 8-12 weeks.
